Description
pam_namespace.c in the pam_namespace module in Linux-PAM (aka pam) before 1.1.3 uses the environment of the invoking application or service during execution of the namespace.init script, which might allow local users to gain privileges by running a setuid program that relies on the pam_namespace PAM check, as demonstrated by the sudo program.
